There are infinitely many axes of symmetry in mathematics.
A trapezium can have at most 1 line of symmetry.
a rectangle has 2 axes of symmetry
It has 5 axes of symmetry
A square has 4 axes of symmetry.
A regular pentagon has five axes of symmetry.
An isosceles triangle definitely has three axes of symmetry
None, normally. One if it is an isosceles trapezium.

None.
Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.
A trapezium prism has one plane of symmetry if the trapezium is isosceles, meaning the non-parallel sides are of equal length. This plane of symmetry bisects the prism vertically through the center, dividing it into two mirrored halves. If the trapezium is not isosceles, it has no planes of symmetry.
